Normal variation mellem 3 til 10 grader.

Øget tibial slope giver øget belastning på ACL/foreste korsbånd, grundet øget anterior translation af tibia både i 0, 30 og 60 grader.

Ved mere end > 12 ° Posterior tibial slope, øges risikoen for graftfailure /re-ruptur med 59 % ( webb et all, Am J Sports Med 2013. 41(12))

 

 

Indikation: For tibial slope recuderende osteotomi:

Revsions korsbånd med 

> 12 ° Postior tibial slope

 

Teknik:

Level IV studie: Combined HTO, ACLR and CR is an effective treatment in these cases. The graft failure rate increases with an increase in tibial slope, in particular when exceeding 12.5°.

There was no significant difference between PTS measurements that used the proximal anatomic axis from lateral knee radiographs and those that used the anatomic axis from full-length lateral tibia radiographs:
